Gauges 40-60-80-100. Flatwound. Rotosound Jazz Bass Strings are the original monel flatwound bass guitar strings.One of the original Rotosound sets from the early 1960s. These strings can be heard on many famous albums, used over the years by Sting, Phil Lynott, Steve Harris and John Deacon.Rotosound makes the world's most famous and highest quality electric bass strings.

I just received my Rotosound SM77 Jazz Bass Strings and installed them on a 90's fender precision standard with a new Gotoh bridge and I am very happy. I play in a country rock group along the lines of 1970?s Bob Dylan, Johnny Cash and The Band. I play with my fingers only and require a clean, smooth sound. My main amp is an Ashdown Perfect Ten combo 30 watt with 10" speaker. I dial the tone controls flat.The Rotosounds have a much lighter tension than Fender flat wounds making them easier to play overall. They are slightly less smooth to the touch than the Fender flat wounds but this is pretty much negligible. If you want bass strings that are the best of both worlds between wound and flat wound these are the strings for you. I am now a Rotosound string user for life.

I put the hybrid set on my home-made fretless jazz bass. Man, these strings sing. Finger noise is non-existent, harmonics are retained, and my fingerboard isn't being gouged!

The tone is similar to RS66s, which I regularly use on my fretted, except for a little lower output and a bit less top-end. The mids are clear and punchy, not wonky or scooped. The jazz bridge pickup solo'd, tone knob halfway, you cannot go wrong.

For flats, they are not perfectly smooth, but they're pretty much a roundwound/halfwound tone in a flatwound package, so a tad bit of smoothness is sacrificed for tone. I personally like the little bit of texture.

I play progressive rock, jazz, fusion, classical, etc and these do half the job for me. I've heard these also work great on P-bass, fretted, and pretty much anything else. Great strings!

have quite a few basses, all with round wound strings, so I just bought a Fender Jazz and I said I wanted to put flat wounds on it to get that real Jazz Bass sound, not only did I get the sound but I noticed how easy they were on my fingers and frets, they have a nice even sound but I was kind of shocked how bright they were for flat wounds, but I liked that, no round wound clatter. Good feeling strings, you know when your fingers hit them.very good quality, nice tone. you get what you pay for, so it was no problem spending a little extra for them.

Just put these on my Jack Casady Epi. I play upright as well and really like the speed and quiet of flat wounds. So, I tried these as a compromise, i.e., not lose the brightness of round wounds but get rid of the clatter and get more speed. And, so far, I am pleased. Rehearsed with the full band with them on and the bass was clear and fast. Type of music: Americana, Blues, Rockabilly, Rock, Jazz. Amp: GB shuttle.

I was looking for bright flats. did a search and these came up. At first they were great so I bought a second set for my other bass. In a couple of weeks the G and D were dead the E and A still sounded OK but when you transitioned to the higher strings there was a loss of sustain and tone. This happened on both guitars, ... weird. I replaced them with D'addario chromes which are a little brighter. I found that the chromes are brighter then what D'addario calls "bright flats" Hope this helps

Just got a Ephi' Goth T-bird bass last month and was looking for a Funky sound and went with the 77's flat's andam really happy with them! Nice easy feel and smooth andyou get a wide sound, from funk with a little growel to a phat full sound having 4 basses with different strings for different tunes is nice gonna stay with these on the T-bird and if You try then you should be happy!!!!! Rock on Dude!!!!

These are extremely great strings. When I buy my new bass, I will have a pack of these strings waiting to go on it. Yes they are expensive, but the sound and quality make them much more than worth it. I definately recommend these strings to anyone that wants their bass to sound good, (or just better.)Ok, I know its sacrilegious, but, I got these strings and put them on my Rogue bass (which is currently my only bass, as I am in the market for a new one). I have to say, it doesn't sound like a beginner bass anymore. It still doesn't sound like a Gibson EB or a P-Bass, but it really doesn't sound bad.The quality of these strings is phenomonal. They are the best made strings I have ever used on one of my guitars. They aren't quite as smooth as the strings I was using on the school's double bass, but so much smoother than ernie balls. I have currently had these strings on my bass for 6 months, with no sign in sight of changing them. If you keep these babys clean, they will last a lifetime (so ive heard).Ok, so value. I would easily invest twice as much for something of this quality and sound. I gave these strings a 10 in value simply because there was no option to put 20.
